The corrosion behavior of ASS 316L laser welded and GTAW welded in lithium bromide concentrations of 0.05, 0.1, 0.5, 1, 3, 4.6, 6, 8.06 and 9.79 M was evaluated using electrochemical methods and optical microscopy. The inhibitors used were: sodium chromate, sodium bromate and sodium molybdate. Optical microscopy showed that ferrite was formed in the austenite matrix exhibiting austenite ferrite solidification. Open circuit potential showed that laser welded had more noble potentials than GTAW welded at most of the concentrations. The laser welded showed lower corrosion currents and corrosion rates than GTAW welded. Moreover, laser welded showed better pitting resistance than GTAW welded, while GTAW welded showed better repassivation behavior than laser welded. The sodium chromate approved to be the most efficient inhibitor. Moreover, laser welded is inhibited more efficiently by the three types of inhibitors than GTAW welded. Laser welding is better than GTAW welding for ASS 316L.
